Justia Opinion Summary: In a wireless system, devices communicate with fixed “base stations” according to “protocols,” which are standardized procedures that govern how data exchanged between devices is formatted, ordered, maintained, and transmitted. Effective wireless communication requires that the transmitting device and the receiving device follow the same protocol. Commil’s 395 patent covers a method of providing faster and more reliable handoffs of mobile devices from one base station to another as a mobile device moves throughout a network area. Cisco is a major supplier of WiFi access points and controllers. A jury found that Cisco directly and indirectly infringed specified claims of the 395 patent; that the specified claims were not invalid as indefinite, for lack of enablement, or as lacking adequate written description; and that Cisco was liable for $63,791,153 in damages and pre-judgment interest and costs. The Federal Circuit reversed in part, holding that the district court gave the jury a legally erroneous instruction concerning indirect infringement and that Cisco’s evidence of a good-faith belief of invalidity may negate the requisite intent for induced infringement. The district court did not err in granting a partial new trial.
